Spinal anaesthesia (or spinal anesthesia), also called spinal block, subarachnoid block, intradural block and intrathecal block, [1] is a form of neuraxial regional anaesthesia involving the injection of a local anaesthetic or opioid into the subarachnoid space, generally through a fine needle, usually 9 cm (3.5 in) long.
Types of epidural needles include: [3] The Crawford Needle; The Tuohy Needle; The Hustead Needle; The Weiss Needle; The Sprotte Spezial Needle; Other Epidural Needles : Other less popular types are the Wagner needle (1957), the Cheng needle(1958), the Crawley needle (1968), the Foldes needle (1973), and the Bell needle (1975)—all variants of the Huber design with a blunted tip of varying ...
In medicine, the Birmingham gauge specifies the outside diameter of hypodermic needles, catheters, cannulae and suture wires. It was originally developed in early 19th-century England for use in wire manufacture, and began appearing in a medical setting in the early 20th century. Another common needle gauge system is the French catheter scale.
An increasing French size corresponds to a larger external diameter. This is contrary to Birmingham gauge, where an increasing gauge corresponds to a smaller diameter needle. The French size is a measure of the outer diameter of a catheter (not internal drainage channel, or inner diameter). So, for example, if a two-way catheter of 20 Fr is ...
Spinal needle. used for puncturing the spinal canal for injection of medications in spinal anaesthesia. Epidural catheter. used to administer medications into the epidural space. Syringe. to inject medications. Mucus sucker. to aspirate any fluid specially mucus from the respiratory passage. Variable performance devices.
However, the standard length of a spinal needle (90mm) may be insufficiently long to reach the subarachnoid space through the Tuohy needle. An extra-long needle (e.g., 120 mm) may be required. Alternatively, several manufacturers produce packs containing both a spinal and an epidural needle which are slightly modified to fit together.
A shallow wheal of local anesthetic is set in the stage of needle entrance. A 6 tsp mix of 5ml of bupivacaine 0.5percent and 1ml of 40 mg/ml of triamcinolone is put in a 10cc syringe. A 20-gauge 3.5 inch regular cutting back spinal needle is directed in-plane under real time ultrasound [4] guidance into the anterior capsular recess. After the ...
Fine-needle aspiration (FNA) is a diagnostic procedure used to investigate lumps or masses. In this technique, a thin (23–25 gauge (0.52 to 0.64 mm outer diameter)), hollow needle is inserted into the mass for sampling of cells that, after being stained , are examined under a microscope ( biopsy ).
